Decimal.ToByte Method (Decimal)


Converts the value of the specified Decimal to the equivalent 8-bit unsigned integer.

Namespace:   System
Assembly:  mscorlib (in mscorlib.dll)

Public Shared Function ToByte (
	value As Decimal
) As Byte


Type: System.Decimal

The decimal number to convert.

Return Value

Type: System.Byte

An 8-bit unsigned integer equivalent to value.

Exception Condition

value is less than Byte.MinValue or greater than Byte.MaxValue.

Parameter value is rounded to the nearest integer value toward zero, and that result is returned.

You can also convert a Decimal value to an 8-bit unsigned integer by using the Narrowing(Decimal to Byte) assignment operator. Because the operator performs a narrowing conversion, you must use a casting operator in C# or a conversion function in Visual Basic.

The following example uses the ToByte method to convert decimal numbers to Byte values.

Module Example
   Public Sub Main()
      Dim values() As Decimal = { 78d, New Decimal(78000, 0, 0, false, 3), 
                                  78.999d, 255.999d, 256d,
                                  127.999d, 128d, -0.999d, 
                                  -1d,  -128.999d, -129d }

      For Each value In values
            Dim number As Byte = Decimal.ToByte(value)
            Console.WriteLine("{0} --> {1}", value, number)       
         Catch e As OverflowException
             Console.WriteLine("{0}: {1}", e.GetType().Name, value)
         End Try   
   End Sub
End Module
' The example displays the following output:
'     78 --> 78
'     78.000 --> 78
'     78.999 --> 78
'     255.999 --> 255
'     OverflowException: 256
'     127.999 --> 127
'     128 --> 128
'     -0.999 --> 0
'     OverflowException: -1
'     OverflowException: -128.999
'     OverflowException: -129
